ios-加載主ViewController

加載主ViewController

有一個root的ViewController 類，調用OnlineViewController的視圖：

- (void)eventTap:(UIGestureRecognizer *)gestureRecognizer {

self.evc = [[EventViewController alloc]init];    
[self presentViewController:self.evc animated:YES completion:nil];
}

嘗試從OnlineViewController中調用ViewController的視圖時失敗了。

-(void ) iconAction{
self.vc = [[ViewController alloc]init];

[self presentViewController:self.vc animated:YES completion:nil];

如何調用ViewController的視圖？

最佳回答：

主viewController 通過presentViewController:animated:completion: 方法彈出新視圖EventViewController 你如果想在彈出的視圖中返回到主視圖,關閉這個彈出視圖即可

在EventViewController 的-(void)iconAction: 中調用

[self dismissViewControllerAnimated:YES completion:nil];
